    Default AC servo Viper drive ... soon

    I'm hoping to have a AC servo drive by the fall 09. With the Viper 200 drives having great success in the last year (knock on wood) , I will make a modular drive that has a separate control and 3 phase power board.

    It will be available in 200 and 350 volt versions. I'm aiming to drive up to 3 kw motors and run directly from 220vac power.

    Excellent. Should be a good spindle drive for smaller machines I would think.

    Any idea what cost ballpark we're talking about?

    Cheers,

    It would be a step-servo AC drive to drive Fanuc, Baldor, Yaskawa, etc AC servo motors.
    There are already a lot of low priced inverter drives (not closed loop though), You can get a nice japanese 3HP inverter drive for about $200, so i won't be competing with that.

    But it could be a spindle drive for a AC motor with an encoder.

    Yes, well aware of the inverter drives. But the lack of closed loop is problematic for many applications. Rigid tapping is mentioned a lot, but even things like lining up the ears on the toolholder for a spindle with ATC is difficult with an open loop inverter drive. Torque at low rpm is another issue for such drives.

    Cheers,

    Default ?

    Is this still happening? Got lots of Fanuc motors from robots so would be really interested in a drive to use them

    Probably not in the near future for the AC drive, since China is dumping AC drives super cheap now, but maybe since i'm now working with the Pic DSP's on a new drive.

    But i have 2 other new drives and stuff that i will have in the fall.

    Due to recent demand, i am working on a 300 volt 3phase drive. It will use a PicDSP and i plan on having a version for Fanuc and Baldor motors . It will be a ble to run off 220V 3phase line voltage .

    Also this drive will be able to run high voltage Brushed DC (up to 250 volt) and replace my V250.
